EN 12482-1:1998

Overview

EN 12482-1:1998 (CEN) specifies particular requirements for wrought aluminium and aluminium alloys supplied in the form of hot rolled strip intended as reroll stock for general applications. The document covers hot-rolled strip with a thickness range of 2.0 mm to 12 mm and excludes hot-rolled strip that will not be rerolled (for example strip intended for special or direct engineering applications).

This standard is adopted nationally (e.g., SIST EN 12482-1:1999) and provides a consistent baseline for suppliers, rerolling mills and downstream processors to assess suitability for rerolling operations.

Key Topics

• Scope and applicability: Defines the form, thickness range and intended use (reroll stock) for hot-rolled aluminium strip.
• Material identification: Requirements for alloy designation and documentation to ensure the strip is suitable for rerolling.
• Quality and surface condition: Expectations for surface finish appropriate for subsequent rolling operations and for removal of defects during rerolling.
• Dimensional requirements: Acceptance criteria related to thickness and width tolerances appropriate for reroll stock (within the covered 2.0–12 mm range).
• Delivery and traceability: Documentation, marking and traceability provisions to link delivered material to production records and quality checks.

Applications

EN 12482-1:1998 is principally used by:

• Rerolling mills and processors selecting hot-rolled feedstock for cold rolling or further shaping
• Material purchasers and specifications teams who require documented assurance that supplied strip is intended for rerolling
• Quality and production engineers who need traceable material suitable for predictable processing behaviour

Typical practical benefits include improved process predictability, reduced rejection during rerolling, and clearer supplier–buyer agreements on material condition and documentation.

Related Standards

• EN 12482 (other parts) - complementary parts addressing different product forms or applications (refer to the EN catalogue for related part numbers).
• National adoptions (for example SIST EN 12482-1:1999) often reflect the same technical content with national forewords or administrative changes.
• Other EN standards for wrought aluminium products and alloy specifications provide context for alloy designations and mechanical/chemical requirements.

For procurement and engineering teams, EN 12482-1:1998 is a practical reference to ensure hot-rolled strip delivered for rerolling meets expected form, documentation and quality levels, reducing processing risk and improving supply chain clarity.
